nope, it can be done through cookies.
not sure of entire details but something along the lines of
- site X sets cookie GotchaMate, being part of a group that harvests
email addresses
- site Y sees you have cookie GotchaMate, uses it to index your
details from group database
There are probably more subtle variations on the theme.
Amazon affiliates use something similar but in their case will have a
"how do I know you're Thom McGrath button?" visible.
